Abstract

This paper is mainly focused on generating a high quality surface on tungsten carbide by micro polycrystalline diamond (PCD) milling tool. Micro milling tools made of PCD are developed. In order to machine tungsten carbide more precisely and more efficiently, systematic experimental procedures have been carried out. The influence of cutting parameters, including axial depth of cutting (a p ) and feed per tooth (f z ), on the achievable surface quality are studied under one-factor variation experimental design. Further tests are also conducted to monitor surface roughness as a function of the machining time. Mirror quality surfaces, with surface roughness Ra around 40 nm are obtained on the machined samples, which could be used as an example of the application of the process in specific fields, such as superior surface finishing.
